I just completed a manuscript which addresses the identificaiton of this group of moths. These Washington Co., OK, examples are indeed good examples of Feather-edged Petrophila. My supposition that they belonged to Heppner's was erroneous. Heppner's remains a locally occurring Texas endemic. Sorry for all my confusion. I address this ID issue in a more recent journal post on iNaturalist.

There are complexities with the barcode BIN BOLD:AAG9560, that are very confusing. If you look this BIN up, most of its public data records (12 of 14) are proper P. fulicalis from Maryland and Virginia. Your two examples from Washington Co., OK, differ very little from those and the images of the specimens should have been enough to convince me (originally) that yours are also fulicalis. However, somehow, your two specimens got labeled as "Petrophila hodgesi", probably due to the proximity of that regional specialty. Thus your two specimens show up when one searches for the taxon "Petrophila hodgesi". The latter search actually brings up public images of seven specimens, five of which are from Washington Co., AR (not OK), and are part of the type series of true P. hodgesi. But apparently none of those specimens have actually been barcoded or the barcodes were unreadable because none of that set of AR specimens are attached to any BIN. That leaves AAG9560, by default, as the only BIN associated (erroneously) with hodgesi.

So the task at hand is to get some of the real hodgesi from the Ozark and Ouachita ecoregion collected, examined, and barcoded. In my recent review of all this, I turned up about 33 observations of good-looking hodgesi (with some overlap of images on iNat and BG) which encompass 15 county-level occurrences in s.w. MO, w. AR, and e. OK (Sexton, in press). In OK, I show records in Adair, Cherokee, La Flore, Mayes, McCurtain, Pushmataha, and Sequoyah counties in OK, but none in Washington Co. Some of those county records are from Nelson's county chart and I have not seen specimens or images firsthand from all these counties.

I have found legitimate(-looking) fulicalis records in the following OK counties: Mayes, Osage, and Washington. Nelson shows fulicalis records also in Adair and McCurtain counties. Those latter records might be correct but those counties overlap the edge of the Ozark and Ouachita ecoregions, so I need to contact Nelson to verify the records.

J-F Landry just updated Petrophila BINs with the same identifications.

After reading all the descriptions in Munroe's MONA fascicle and checking habitats and ranges, it appears fairly likely that any of the "fulicalis-like" Petrophila's in the Ozark ecological region of Arkansas, Missouri, and e. Oklahoma are likely to be the regional species Petrophila hodgesi. I'm still working through all these, concentrating primarily on Texas material, so I can't say definitively.
